SF-1P Reciprocate Pb-free Self-lubricating Bearing

Reciprocate Pb-free Self-lubricating Bearing

Features

The Product is developed according to reciprocating motion of shock absorber and high pressure in flank. It can offer low friction coefficient and good anti-abrasion, be used in semi-dry condition. The product is applied to shock absorber of automobiles, motorcycles and pneumatic cylinder.

Material Structure

  1. PTFE with CU 0.01~0.03mm
  2. Porous bronze 0.2~0.3mm
  3. Steel backing 0.7~2.3mm
  4. Tin-plating 0.005mm or copper plating 0.008mm

Available forms

Bushes, flanged bushes, WC thrust washers, strip and other non-standard parts and so on.

Application Feature

  • It is efficient even under sudden break off the lubricating oil, wear resistant, and so can keep the lubricating oil clear after long period of working.
  • It can protect the mating surface from wearing.
  • It is particularly suitable for bushes in reciprocating motion.
  • It is suitable for the machine requiring harmless to people because of lead-free.
  • It is used in shock absorber of motorcycles and various hydraulic cylinders, hydraulic motors and pneumatic elements etc.
